I did not spend a lot of attention to my transfer vessel parked in a save mun-orbit at around 40.000m . I can only assume that it changed it´s orbit even when inactive and crashed into the mun, same as some empty boosters did earlier today. They kept changing orbit as I got rid of them at aprox. 100km above Kerbin instead of moving along the initial predicted orbit.

Description of the bug.
Expected Behavior >> stable orbit of decoupled rockets and rocket parts
Observed Behavior >> orbits change without added energy >>see above
>>>>
Found a quicksave and saw the return vessel approaching the mun surface. The orbit did change!
Next Bug (within that quicksave file) is that my lander after swiching to returnvessel and back startet to rise in altitude with shut off engines. No relative movement to ground, just straight up!!!
